Ufakelo lwevalve yolawulo lombane kunye nokulungiswa kwevalve yolawulo lombane uphawu oluhambelana nevalvu yokuvula Ufakelo lwevalvu yokulawula Umbane kunye nolungiso Phambi kofakelo lwevalvu yolawulo yombane kufuneka ufunde ngocoselelo ikopi, unikezelo lwamandla olufanelekileyo kwaye kufuneka lufakelwe ngabasebenzi abaziingcali kunye nobugcisa. Indlela yokuhamba kufuneka ibe kwicala elinye kunye notolo olukumzimba wevalvu. Umzimba wevalvu uya kubekwa ngaphezu kwepleyiti yokufumana amanzi yekhoyili ukuqinisekisa ukuba amanzi awela kwipleyiti yokufumana amanzi. Umzimba wevalvu kunye nomqhubi kufuneka afakwe kwicala elithe nkqo le-60 ℃ uluhlu, okungentla kufuneka kube ubuncinane be-30mm indawo yokuqhaqha. Indawo yolawulo eyaneleyo kufuneka igcinwe kunye nemibhobho ekufutshane, izixhobo kunye nezakhiwo, kwaye kufuneka kufakelwe apho abasebenzi bolondolozo banokufikelela khona ngemingxuma yokuhlola. Faka umqhubi kuphela emva kokuba umzimba wevalve ufakiwe kwaye umbhobho uphumelele uvavanyo loxinzelelo. Ukuba umqhubi ufakwe kumzimba we-valve, ungasebenzisi amandla kumqhubi ngexesha lofakelo kunye nokugunyaziswa, ngaphandle koko umqhubi uya konakala. Emva kokufakela kwaye ujonge ukuchaneka, ukulungiswa kwamandla. Ubuncinci imijikelo emithathu epheleleyo yokusebenza yomqhubi kufuneka iqwalaselwe de zonke iinxalenye zichanekile. Emva kokuphumelela uvavanyo lwamanzi, uvavanyo lwamanzi luya kwenziwa. Ukwahlukana koxinzelelo phakathi kwamanzi angaphezulu nangaphantsi kwenkqubo kufuneka kulawulwe ngokungqongqo ngaphakathi kwe-0.15MPa ukuqinisekisa ukusebenza kwevalve yokulawula umbane kwi-switch flow flow. Isignali yevalve yokulawula umbane ehambelana nokuvula ivalve Umbane wokulawula ivalve Umbane ohambelana nomboniso wokuvula ivalve: Ivalve yokulawula umbane ngokwamkela isixhobo sokulawula ukusuka kumqondiso we-4-20MA, ukugqiba ukulawula okuphakathi kwipayipi, ukuhamba, ubushushu. Ke ingakanani ivalve yokuvula ehambelana ne-4-20MA yesiginali yangoku, kwaye yintoni indlela yokuguqula? I-valve yokulawula umbane ifumene umqondiso kunye nendlela yokuguqula evulekileyo: xa i-valve yokulawula umbane ukwamkela umqondiso wangoku ingaphantsi okanye i-4MA xa i-valve ivaliwe. Ukuvulwa kwevalvu yi-6.25% xa isignali yokufumana i-5MA. Indlela yokuguqula kukukhupha isignali ye-20MA kwisignali evaliweyo ye-4MA, eyi-16MA uphawu oluvulekileyo. Eyona nto ingcono yokulawula ivalve yokuvula yahlulwe ngokuvulwa komqondiso we-16MA efunyenweyo akukho mqondiso ovulekileyo we-MA yi-6.25%. Isignali yevalve yokulawula umbane ehambelana nenkcazo yokuvula i-valve: Oko kukuthi, xa uphawu lwangoku luyi-8MA, i-valve ivulwa ngekota enye kunye nokuvula i-25%; Xa uphawu lwangoku luyi-12MA, isiqingatha sevalve sivulwa, kwaye idigri yokuvula i-50%. Xa uphawu lwangoku luyi-16MA, i-valve ivuliwe kwiikota ezintathu, kwaye ukuvulwa ngu-75%; Xa isignali yangoku i-20MA, i-valve ikwimeko evulekile ngokupheleleyo kwaye idigri yokuvula i-100%. Olu lwazi lungentla lwevalvu yolawulo ngumvelisi wevalvu yolawulo oluchwepheshile eShanghai - iShanghai Taichen Valve Co., LTD.
